We don't support this API version. Use API version 32.0 or later to retrieve this process

Question

I'm using the Salesforce Migration Tool (Ant) to deploy Salesforce changes. When I retrieve my changes, all changes are pulled down (even other flows/processes) except for one, which throws this warning/error:

retrieveCode:
[sf:retrieve] Request for a retrieve submitted successfully.
[sf:retrieve] Request ID for the current retrieve task: 09Sq0000005aYGYEA8
[sf:retrieve] Waiting for server to finish processing the request...
[sf:retrieve] Request Status: Pending
[sf:retrieve] Request Status: Succeeded
[sf:retrieve] Retrieve warnings (1):
[sf:retrieve] package.xml - We don't support this API version. Use API version 32.0 or later to retrieve this process: My_Fancy_Process-18
[sf:retrieve] Finished request 09Sq0000005aYGYEA8 successfully.

BUILD SUCCESSFUL
Total time: 12 seconds

This message is grossly vague, and I'm not finding a single hit about it on the web.

I verified I am using version 38.0 of the ant-salesforce.jar file. My package.xml version is 36.0.

Does anyone know how to get past this?

Answer 1

As it turns out, I needed to update my package.xml version to 38.0. After doing so, the process retrieved fine.

I cannot say for sure but I believe the issue was due to the offending process being marked as Invocable, which may be incompatible with version 36.0 of the API.

Answer 2

Looks like you have a metadata component that your package.xml has reference which is of version higher than 32 and your ANT jar is still using version 32 or other reason could be your package.xml file has version as 32 specified .

The resolution would be update your ANT jar library to recent version if jar is not latest and if package.xml is using version 32 just bump the version of the jar to 35 or 36 and you should be good .
